Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Construction of a Triangle Similar to a Given Triangle, Tangent at a Point on a Circle Using the Centre, Tangent at a Point on a Circle Without Using the Centre.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 44 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

4
Day 7

Spaced Revision

Come back to Geometric Constructions after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Similar triangles have equal corresponding angles.
  • Similar triangles have corresponding sides in the same proportion.
  • Construction is done in two cases: distinct vertices and one common vertex.
  • A line perpendicular to the radius at its outer end is a tangent to the circle.
  • If CP is a radius and P is on the circle, then the perpendicular through P is the tangent.
  • The construction uses the centre of the circle.
  • This construction does not use the centre of the circle.
  • The tangent-secant angle theorem gives angle CAB congruent to angle BCD.
  • The converse of the tangent-secant theorem proves that line CD is the tangent.

Common Mistakes to Avoid

A tangent at a point on a circle can be drawn by guessing any line that touches the circle.

Without using the centre, the tangent can still be constructed by drawing a radius from the point of tangency.

The same letter always means the same point everywhere in the chapter.

Memory Tips

Construction of a triangle similar to a given triangle uses two cases: vertices distinct and one vertex common

Corresponding sides of similar triangles are proportional and corresponding angles are equal

Construction of tangent at a point on a circle using the centre

Perpendicular to the radius at the point of contact gives the tangent
